It's likely a font problem. Do you have OpenOffice installed? It adds a font called Deja Vu that has caused crashing in the past.
Regardless, you'll have to troubleshoot your entire font collection; I recommend obtaining a font manager like FontFrenzy (free).
Thanks for the suggestion, we tried font frenzy and just left the system fonts, but problem still occurs
Then I'm out of ideas. The only reason I've encountered for the titler to crash is missing or corrupt fonts.
Does the titler crash in a brand-new project?
yes it does crash in a new project
